Abstract

An apparatus includes a data storage media and a plurality of heads, the data storage media and heads being structured and arranged for relative movement between the heads and storage media causing the heads to move along a scan path, and an actuator for changing a magnitude of head to media force as the heads move along the scan path. A method for reducing head motion hysteresis is also provided.
